At the Roggenhausen Wildlife Park you can observe rabbits, ponies, goats, sheep, wild boar, deer, ibex and many other animals from up close.
Secluded paths along the riverbanks contrast with centuries old small towns. The river landscape presents its romantic side and then again its natural side, and in the thermal spa its more zesty side. Towering above all this are mighty castles and palaces.
Well worth a visit are such historic buildings as the Obertorturm (Upper Gate Tower), the Obertor (Upper Gate), the 15th-century Stadtkirche, the Gerechtigkeitsbrunnen (Fountain of Justice) and the Landjägerwache.
